Abstract (in Japanese) (See Japanese page) 
(in English) In order to maintain and improve health, it is very important to grasp one's eating habits in his/her everyday life. However, it is not easy for an individual to continuously record his/her dishes in the long term. In this paper, we propose a method to predict individual long-term food records only by short-term records, and aim to grasp one's eating habits. In order to estimate the number of times the user ate each meal, we proposed a collaborative filtering considering time property and personality. In experiments, we improved an accuracy of RMSE by 10.8% compared with a baseline.
